TYPE-WRITING MACHINE.

Application filed. January 15, 1915.

To all whom it' 'may concern:

Be it known that l, EDWIN E. BARNEY, citizen of the United States, andresident of llion, in the county of Herkimer and State of New York, haveinvented Acertain new and useful Improvements in Type- VVritingMachines, of which the following is a specification.

My present invention relates to ribbon mechanism for typewritingmachines and its general obj ect is to provide improved mechanism of thecharacter specified. More particularly one object of the invention is toprovide new and improved means for varying the vibratory movement of theribbon so that dierent widthwise portions or color fields may beemployed at will; another object is to provide new and improved ribbonsto i devices; and a still further object is to pro de novel devices fordispensing entirey` with the use of the ribbon so as to facilitate, forexample, the writing of stencils.

To the above and other ends my invention consists in the features ofconstruction, combinatians of devices and arrangements of partshereinafter described and particularly pointed out in the claims.

ward, the views showing the parts in the different relationships inwhich they may be set.

As appears from Figs. 1 and 3 the main frame of the machine comprises abase 1, Iposts 2 and a top plate 3 which support fixed guide rails t,said rails cooperating through anti-"friction balls 5 with a carriagetruck 6. A platen 7 is mounted in a platen frame 8 which is shiftablyconnected with the truck 6 by devices 9 so that said platen frame may bemoved up and down to shift the platen and thereby change case. Saidplaten frame comprises 'a cross bar 10 on which is journailed a roller11 that is adapted to run on a shift rail 1Q supported by upright arms13 rising from a transverse bar 14 which in turn is supported on uprightarms 15, each arm 15 being pivoted at its lower end at 16 to a lever 17provided with a shift key 18. The platen normally stands in lower caseposition but may be raised or shifted t0 upper case position by`depressing either of the shift kevs 18 which thus control the shiftingmovements of the platen through the shift frame comprising the rail 12,cross bar 14 and pairs of arms 13 and 15. Printing key levers 19 areprovided with keys 20 and are connected by links 21 with sub-levers 22,said sub-levers in turn being connected by links 23 with front-striketype bars Q4 mounted on hangers secured to a stationary segment orsupport 26. A universal bar 27 underlies the key levers and is supportedon arms 2S depending from crank arms 2.9 which project rearward from atransverse rock shaft 30 having end pivots supported in the sides of thebase. Projecting from said rock shaft' near its middle is an arm 31which is connected b v a link 32 with certain eseapement devices (notshown) but which are preferably of the usual construction. Ribbon spools33 are supported. one at each side ofthe machine. above the top plate onshafts 34 and a ribbon IE5 is wound ony said spools and fed upwardtherefrom through openings 236 in the lop plate.. thence over stationaryguides 37 and through a ribbon vibrator. hereinafter described. arrangedcentrally between said guides. Wenns for turning the ribbon spools inalternation to feed the ribbon longitudinally back and forth operate onthe shafts 34, whirh shafts bear in lugs 38 depending from the top plate`and extend fore and aft of the machine. The ribbon spools are supportedon the front ends of these shafts while their rear ends carry beveledpinions 39 which are adapted to mesh with beveled pinions 40 mounted o na ribbon driving shaft 41 bearing in stationary lugs 42, one pinion 40being disposed near each end of said shaft. The driving shaft isconnected through intermeshing beveled pinions 43l and 44 with a springdrum 45 in such a way that when the carriage comprising the truck 6 andplaten frame 8 is drawn leftas best appears from Figs..4, 5 and 6, a

body portion 47 of sheet metal from which depends a narrow integral stemportion 48. The sides of the body portion are curled or rolled, asindicated at 49, to provide tubelike portions which receive upstandingwires 50, the upper ends whereof are bent to provide guide loops 51through which the ribbon is threaded. The wires 50 are frictionally heldin the tube-like portions 49, the

loops 51 and the printing portion of the ribbon which extends betweenthem. The construction provides a vibrator which is simple andinexpensive, is light in weight, and affords a ready relative adjustmentbetween the body and stem on the one hand and the head comprising thewires 5() on the other. The stem 48 at its lower end is curled aroundand pivotally supported by a pivot pin which is mounted on the forwardend of a. horizontally disposed arm comprised in a ribbon operatingmember or icver frame 54, said frame further including laterallydivcrging branches 55 and a central downwardly extending arm 56terminatH ing in a rolled or cylindrical end portion 57. The branches 55are curled around and frictionall)r hold a pivot pin 58 which ispivotally supported on a guide frame which is designated as a whole bythe numeral 59. Said guide traine comprises two parallel side arms 6!)connected at the top and bottom by inn-gral er ss bars numberedrespectively 431 and 62. Extending upward from the cross bar 62 are lugs63 which are inclined rearward behind the rail 12 and receive screws 64by which the guide frame 59 is fixed to said rail. The ends or sides ofthe cross bar 62 terminate in rearwardly bent ears 62 which are formedwith bearing openings in which the projecting ends of the pivot rod 58are journaled. The arms 60 in oline upward and forward in front oftherail 12 so that the cross bar 61 is at the front side of the platen.Said cross bar near its ends islcurved forward laterally and terminatesin upstanding guide fingers 65 behind which the ribbon passes before itreaches the vibrator, said fingers pro` viding a guide for the ribbon inthe vicinity of the vibrator and which remains stationary duringvibratory movements of the vibrator and lever. Depending centrally fromthe cross bar 61 is a lug 66 which provides a support for a headedshoulder screw 67, said screw extending through an elongated verticalslot 68 cut in the body 47 Vof the vibrator. The sides 68 of the slotare formed by bending back the metal from the slot opening so as toprovide smooth and comparatively wide surfaces for coperation with thesides of the guide screw 67. 1t will be observed that the guide frameV59 which. is supported on the platen-shifting frame and shifts with theplaten combines several functions, as it provides a pivotal support forthe operating lever, a guide' for the vibrator and also guides for theportions of the ribbon which extend from the vibrator to the spools ormore directly tothe stationary guides 37.

The operating lever and vibrator are adapted to be actuatedfby anactuator or lever member which is mounted to shift auton'latically whenthe platen, the vibrator and the operating lever are shifted, but to aless extent than these three elements. In other words, the actuatorreceives a differential shift. The purpose of this, as will more clearlyappear from what follows, is to compensate as between theoperatingleverv which shifts with the platen and the element from whichthe actuator itself receives motion and which does not shift at all. Theactuator' or sub-lever, designated as a whole by the numeral 69. isvertically disposed behind the shift bar 14 and is preferably formed ofsheet metal, its upper end portion providing a con'iparatively broadface 69 for copcration with the round end 57 of the operating lever. Thelower end or arm of the sub-lever has a lateral slot 70 below which themetal bent or shaped, so as to provide at thc left-hand side a step orface 7.1` which is behind the surface or face 72 at thc right-hand side,said face 72 being in the general plane of the sub-lever. The two facesare adapted to copcrate separately with the rounded upper end of a keycontrolled oi'ierating finger or device 73 which as clearly shown inFig. 1, rises from the crank arm 31 to which it is fixed by rivets'being pivoted between its ends.

74. The sub-lever -69 is of the irst order, For this purpose aboutmidway of its length it is provided at its side edges with rearwardlybent, perforated ears 7 which receive and bear rotatably ona pivot pin76. This pivot pin is supported on a bracket, bearing member or slide,designated numeral 7 7, best shown in Figs. 4 to 7. Said member 77comprises a horizontally dis- Josed body portion or slide bar proper 78from the middle of which rises anupright portion 79 terminating at thetop in a forwardly bent slotted lip 80 which receives the upper end of aguide finger 81 that is screwed or otherwise secured to the top of thebar 14. This guide finger serves as well to support the slide 77 andprevent it from pulling away toward the rear through'gravity. rl`heportion 79 is provided at its sides with rearwardly bent parallel ears82 which loosely embrace the ears 7 and support the ends of the pivotpin 7 (3 which project` beyond said ears 7 The body portion 7 8 isprovided near its ends with horizontal slots 83 which receive headedsupporting and guiding screws 84, said screws being threaded int-o linksorv arms 85 about midway of their lengths. Each link 85 is lpivotallysupported at its inner end on a shoulder screw 86 which is threaded intothe rear of the shift bar 14, the two screws 86 being close together andbehind the middle portion of the slide. The outer ends of the links 85are pivotally anchored at 87 to stationary supports or angular brackets88 suitably secured to the under side of the top plate and incliningforward and downward therefrom. It will be understood that the outerends of the links 85 have fixed pivots as distinguished from their innerends which have shiftable pivots, being supported on the Aplatenshifting frame. The screws or supports 84 are fixed or supported at suchpoints on the links 85 as to receive half the amount of shiftingmovement which the platen shifting frame comprising the shiftable bar 14receives when one of the keys 18 is depressed. Consequently the slide 77which is mounted or supported on these screws 84 wil-l, together withthe sublever G9, be shifted differentially or to half the extent thatthe platen. together with the ribbon vibrator and operating lever, isshifted. In other words, when the operating lever 54 is shifted the fullextent of the platen shift the sub-lever G9 which operates on saidoperating lever will be shifted only half as far and as a result of thisthe length of the load arm of the lever or .the distance from the pivot7 6 to the point of engagement with the lever end 57 will be increased.However, the length of the power arm or the 'distance from the pivot 7 6to the point of enas a whole by thehand front post 2.

`device or actuator 73 to the operating lever 54 through the sub-lever69. In other words. since the finger 73 has a constant movementcommunicated to it from the action of the printingl keys on theuniversal bar, the operating lever 54 and ribbon vibrator will receive acorresponding constant throw or extent of movement in spite of the factthat the vibrator and operating lever shift to change case while theactuator 73 is nonshifting. This result is due to the fact that thedevice or element 69 which is interposed between the operating .fingers73 and the lever 54 and transmits movement from one to the other has adifferential or compensatory shifting' movement as contrasted on the onehand with the lever 54 which has a greater shifting movement and on theother hand with the finger or lever arm 73 which has no shiftingmovement. In lower case the links 85 incline downward from their pivots87 so that they are at an angle below the horizontal lines adjoiningsaid pivots. As a result, however, of the upward shifting movement thelinks will be swung up until they are at an equal angle above thehorizontal line.

The slide 77 is so mounted that it may not only be shifted up and downwith the platen butmay also be shifted sidewise at right angles to thismovement so as to move the sub-lever back and forth from side to sideand bring either one of the steps 71 or 72 opposite the finger 73 forthe purpose of varying the ribbon throw and changing the ribbon fields.Also a further lateral movement may be communicated to the slide andsub-lever in order to carry the latter completely out of the field ofoperation of the finger 73. The means for thus laterally shifting theslide and sub-lever extend to the front of the machine and comprise, asshown in Figs. 1 to 4, a link or bar 89 which is pivotally connected 'atits inner end at 90 to a lug 78 rising from the left-hand end of theslide bar -7 8. The outer end of the link 89 is pivotally connected at91 to a crank arm 92 rising from and fixed to the rear end portion of arock shaft 93 that extends fore and aft of the machine at its left-handside. The rear end portion of said rock shaft bears in an alignlarbracket 94 secured by screws 95 to the under side of the segment 2G,while the forward end portion of said rock shaft 93 bears in a plate 9Gsecured by screws 97 tothe left- Forward of said plate, the rock shaftis provided with a knurled button or finger piece 98. Behind the iingerpiece a pointer 99 projects radially from the rock shaft and 'cooperateswith indicati ated type bar.

ing marks vor devices 100 on the plate 96. The middle mark 100corresponds to the upper field of the ribbon 35 which, in the presentinstance, is preferably a bi-coler ribbon, the upper stripe or field Lbeing black and the lower field Z) being red. llVhen the pointer 99 isbrought opposite the lowermost indicating mark as in Fig. 2 the shaft 93will be turned so that the slide 77 and the sub-lever carried by it willbe drawn to the position shown in Figs. 3, 5 and 8 with the forwardstep` 72 lopposite the finger 73. The slide and sul)- lever, togetherwith the connected parts including the rock shaft 93, will be maintainedset in this position by detent devices comprising a lug or roundedprojection 101 on the rear face of the bracket 94. This projection isadapted to coperate in turn with three holes or openings 102 formed in aspring detent plate 103 screwed or otherwise fixed to the rock shaft 93behind the bracket 911. In the present instance the rightlhand hole 102is engagedl with the lug 101, thus fixing the rock shaft and through thecrank 92 and link 89 setting the slide and the sub-lever in apredetermined position laterally of the finger 73 and the operatinglever 54:. With the parts thus arranged, an actuation of one of theprinting keys 20 will operate through the universal bar and connectionsto swing the finger 73 rearward. Normally the finger is slightlyseparated from the operating face 72 as shown in Figs. 1 and 6 so thatthere is a slight lost motion before the finger picks up said lever andswings it on its pivot, causing the upper arm of the sub lever acting onthe operating lever to lift the vibrator and move it upward to interposethe ribbon in the path of the oper- The parts are so proportioned andarranged that this upward movement will carry the ribbon far enough topresent the lower field b to the types; and so long as the parts remainset as described this throw of the ribbon will be constant for eachactuation of a 'printing key with the result that the type impressionswill follow a straight path` along and centrally of the ribbon field Z).lt will be understood that the shifting of the platen to upper caseposition and the consequent shifting of the parts, as illustrated inFig. 5, will not affect the extent of ribbon throw which will be thesaine as in lower case position. The ribbon vibrator will be shiftedupward with the, platen and to the same extent, so that the nornmlrelationship between the vibrator and the platen will be the saine inupper ease as in lower case position.

lWhen il, is desired to use the upper field a of the riobon 35 the roelr.shaft 93 is turned thro h the finger button 9S until. the pointer isbrought opposite the iniddle indicating mark 190.. The turning movementof the rock shaft acting through the crank arm 92 and the link 89 willshift the slide 77 laterally toward the right. As a result the sub-lever69 `will be shifted rightward until -the operating face 71 at its lowerend will be brought opposite the finger 73, as shown in Fig. 9. r:Eheface 71, it will be noted, is in, a vertical plane somewhat behind or inrear of the face 72 so that as a consequence of thel resetting theinitial lost motion between the finger 73 and the sub-lever will beincreased, resulting in less movement being communicated to thesub-lever from said finger. The

face of the upper end 69" of said sub-lever is in a single verticalplane throughout its width so that its fore and aft relationship withthe operating lever 54: will not be affected b y the lateral shift. Theribbon throw changing devices will be maintained set in their newpositions by the detent devices 101 and 103. the lug or detent 101 beingat this time lengaged with the middle hold in the detent plate 103. Withthe parts thus set an actuation 'of a printing key, acting through thefinger 73, will as stated. communicate less movement to the sub-lever,and as a consequence less motion will be communicated to the operatinglever and vibrator. The parts lare so proportioned and adjusted thatthis movement will raise the vibrator and throw the ribbon far enough tobring the upper field a opposite the printing point and into the path ofthe operated type bar. Since the throw will be constant as long as theparts are maintained thus set and whether the platen is in lower orupper ease position the type impressions will 'follow a straight pathlengthwise of the field a and about fentrally thereof.

Should it be desired to dispense entirel \v with the use of the ribbonwhen the type bars are actuated, for the purpose of writing stencilsheets or for any other desired purpose, the finger button 9S isturuedto bring the pointer 99 opposite the uppermost indicating mark [00. thisresulting in a turning of the rork shaft and a consequent set-- tingthereof with the detent v)101 engaged with the left-hand detent holeV102. .\s a consequence the slide 77 will be moved to its extreme,right-hand position and the sul lever 69 will be carried rightward pastthe linger 73 and set as `shown in Fig'. l0. so that at printingoperations the linger will move idly without all'eeting the subdever orribbon vibrator1 these remaining quiescent and lnuintuiniug the ribbonbelow the printing point.

ln order to limit positively both the up und the down movements of theribbon rar rier or vibrator when it. is vibratori during printingoperations, .stop devices are pio ios body portion 105 which embracesthe front and under sides of the shift bar 14'a11d is slidably mountedon said shift bar by headed screws 106. which pass through elongatedslots 107 formed in the front wall of said body portion and are threadedinto the front of said bar 14. Between the under side of the part 105and the bottom face of the bar 14 is interposed a flat friction spring108 (Fig. 7 the ends of which are bent downward and take into holes inthe under side of the part 105. There may also be provided a leaf spring109 secured as by screws to the under face of the bar 14 and having itsfree end pressing upward against the under part of the body 105.Connection between the supporting frame 104 and the slide 77 is providedby means of an angular finger 110 which extends upward and is then bentrearward from the righthand end portion of the body 105, as best shownin Fig. 4, said finger engaging loosely in a vertical slot 111 cut in alug 112 rising from the right-hand end of the slide bar '78. Theconnection is such that the frame 104 is compelled automatically toslide lengthwise of the bar 14 whenever the slide 77 is shiftedlaterally but the frame 104 and the slide 77 may be shifted up and downdifferentially when the platen is shifted, the frame 104 participatinginthe full extent of the platen shift 'while the slide 77 is shifted to aless extent. Rising t centrally from the body portion 105 integral arm113 which is bent or ofi'- fmrward, said arm providing a support thestop device proper v114. lnaid stop device is adjustably secured to thearm 113 by pivot screws 115 which are threaded into the arm, and passthrough elongated vertical slots 116 in the uprit l t body portion ofthe device. 114, thus `ing fine up and down adjustments o device 114 inas sembling the mechanism. From the body portion of the device 114extend leftward two stop arms 117 and 118. The lower arml 117 isprovided at its outer end with a depressed portion 119 while the upperarm terminates in a lug 120 which projects downward just to the right ofthe depressed end 119. The arms 53 of the operating lever extendsforward between these two arms 117 and 118. said arms providing stopsfor positively arresting the operating lever and vibrator in bothdirections of their movements. Normally the operating lever engageswith. the arm 117 which limits its downward movement and also maintainsit in proper normal relationship with the platen when the latter is inlower case position, and also supports and raises the operating leverand vibrator' when the platen is shifted to upper case position.Preferably a spring tongue 121 is suitably secured to the under face ofthe arm 53 and is interposed at its free end between said arm and thestop arm 117 to act as a cushion between the parts and to eliminatenoise. lVhen the sub-lever is set as in F ig. 8 to give the vibrator itsgreatest throw, the bottom edge of the stop arm 118 underlies the arm 53which will contact with it at the end of the throw so as to insure thearrest of the printing portion of the ribbon with the field opposite theprinting point. When the sub-lever is shifted to give the short throw ofthe ribbon, the stop device 114 is correspondingly shifted to bring thelug 120 over the arm 53, this lug being adapted to arrest the operatinglever and vibrator at the completion of the short throw of theribbonwith the upper field@J opposite the printing point. It will' beobserved that while the stops for arresting the printing movement of thevibrator are 1n different horizontal planes, one above the other, thestop arm 117 Y is inthe same horizontal plane for both these throws, sothat the normal position of the operating lever 'and vibrator isunaltered by the throw changing operation. However, when the sub-leveris shifted to the Fig. 10 position to provide for mimeographing, thestop device 114 will be automatically moved rightward far enough tobring the lower step 119 under the arm 53 which will drop downward bygravity to this lower position, carrying with it the ribbon vibrator andribbon. The consequence is that when mimeographing, the printing portionof the ribbon is slightly lower than it is ordinarily the result beingthat sufficient clearance is insured for the types when they are thrownto the printing point and they are thus prevented from accidentallycatching on the upper edge of the ribbon during mimeographing or stencilwriting operations. The edge 122 lioining the lower step 119 with thearm 117 is inclined downward toward the left so that in moving the stopdevice toward the left and resetting the sub-lever in l a ribbonvibrator, an operatinglever, devices for actuating the operating levercomprising a second or sub-lever, and means :tor eil'ecting a relativeshift between the two levers in order to vary the throw of the operatinglever, such relative shift being brought about in the present instanceby shifting the sub-lever laterally or `transversely of the operatinglever 'through means extending to the Afront ofthe machine andterminating in a nger piece or button, as 98; that said sub-lever isupright and is slidable laterally and settable in predeterminedpositions to vary its effect on the operating lever and is also settablein a position where it is ineective on the operating lever; that theribbon vibrator' brator, being substantially halt' that of the.

vibrator; that the sub-lever is an actuating device which isintermediatetlie shiftable ribbon vibrator and a non-shiftablekeyoperated actuating device, viz., the finger 73; that the sub-lever ispivoted on a bracket which has a pin and slot connection with each oftwo links at points about midway of the lengths of the links, thisconstruction affording a shifting up and down movement of the sub-leversimultaneously with the links and vibrator' and also permitvting alateral sliding movement of the sublever and its bracketi independentlyboth of the links and the shiftable platen; and

vthat ribbon stop devices are provided including variable stops to limitvariable movement of the ribbon toward the printing point as well as tovary its point of arrest during movement in the opposite div rection.
